The secret of this program is the 7 power intervals that push you to new levels of cardio training during the 40-minute section. With an on-screen timer, it’s easy to pace yourself and progress at your own level.

Feel motivated and confident to get the best results ever. Fitness Magazine voted this "the most intelligent workout video of the year".

DVD Bonus: I've broken this routine into shorter segments so you can use the Mix & Match button to shoot straight to the parts you like best.
